Patented Oct. 1l, 1932 stares assists* eraan aries COMPANY, OF CROMWELL, CONNECTICUT, CORPORATION MACHINE GUN v TOY EISYTOL Application filed August 15, 1930. Serial No. 475,489.

My invention relates to improvements in machine gun toy pistols of the form that is adapted to re paper caps in strip form by the operation of a crank, and the obj-ect of my improvement is to produce a machine gun toy pistol that'comprises a complete andffully operative trigger ring toy tape pistol, such for instance as the pistol structures shown and described in applications filed by myself that issued as Patent No. 1,674,429, June19, 1928, and No. 1,691,237, November 18, 1928, and in which is provided additional mechanism for use in firing by the crank.

In the accompanying drawing Figure 1 is a side elevation of my improved machine gun toy pistol, the barrel portion being directed towards the left showing exposed in anropening in the casing adjacent the end of said barrel portion one end of the bearing barrel of the star-cam member that is rotated to effect the firing by the crank, the lotding chamber cover'being swung to one si e. i Y Fig. 2 is a'fragmentary view of the other vside of the barrel end portion, the crank being shown by broken lines. f

Fig. 3 is a view on anenlarged scale showing the right casing member andthe operating mechanism'in position therein.

Fig. 4 is asimilar view showing the starcam member, the slide that is operated thereby, and the trigger member in a different position.` Y A Fig. 5 is a sectional view through the starcam member with the Vkey-portion ot the crank in engagement therewith. Y

Fig. 6 shows the driving end portion of the cra-nk and the lug structure thereon.

Fig. 7 shows the key-entrance portion ,of the -casing and 'of the bearing barrel of the star-cam member. v In operating my improved machine gun toy pistol for rotary or machine gun firing a crank 10 is inserted in an opening 11; adjacent'the outer end of the barrel portion 12 of the pistol `structure so as to make drive connection with a star-cam member 13 for rotating Vthe latter and intervening means effect the liring by operating the trigger member 24, thev portion 15 of the latter that is adapted to be engaged vby the finger r-for linger firing and thus serves as the trigger `proper being exposed and visible as usual within the space 16 that isenclosed by the guardA 17. Y

ln the form that is shown the finger operated firing mechanism corresponds to that of the patents mentioned and the difference in outside appearance is conlined tothe opening 11 mentioned and the end portions ofthe barrel bearing 18 of the star-cam member 13 Y that are exposed therein at the two endsof said opening 11. i

At the left end of said bearing barrel 18 is a plain short cylindrical bearing 19 that merges with a shoulder 20 at the junction with the body 21. VAt the right end 22 is what is operatively a similar bearing, but which is provided with a key-slot 23 for drivingengagement with la radial drive lug 7 24 on the body 25 of the crank 10. The wall structures 26' of the casing27 are suitably spaced apart and of proper thickness so as' to operatively hold and guide the bearing barrel 18 under operative conditions.v -j

The key slot 28 extends inwardly along the bearing barrel 18 beyond and across the end bearing 22 and across the adjacent portion of the body 21 and beyond the supporting Wall v26; the lug 24v also extends inwardly along the crank body 25 to correspond; and the inner end portion of said lug 24 is provided with an extension 27 that projects ra dially outwardly beyond` the adjacent portion of the lug 24. VSaid extension 27 lserves as a retaining lug to prevent removal of the crank 10. i

The opening 11 in the wall structure 26 at the right crank-receiving side besidesthe Y A circular form for providing the supporting bearing for bearing barrel end 22 is provided witha radial slot 28 for admitting the extension to the open space 29 at the inner side of the side wall 26. Thus thee'xtension 27 i's adapted to rotate in said space 29 when the crank body 25 is rotated and at the same time will engage with the opposed inner face of the side wall portion 26 to prevent .outward movement and thus prevent removal of the crank. That is to say, such removal means for of the crank 10 is prevented at all positions of the crank as it is rotated except when the extension or holding lug 27 `is in registration with the admission slot 28 in the casing wall 26.V Under conditions ofvuse, as the crank is rotated, the holding lug 27 is continually carried momentum past the admissionslot 28 so that it operates virtually as a positive the crank.V

. l `Atthe middle of the bearing barreli18 is '5 the star-cam structure which'comprises,. asVV a set ofthree saw-tooth' teeth 130' shown,

y spaced around the body21.` e 1- The teeth drive thev trigger rmemberr 14 through the medium owa slidelgthatghas onone edge a vdrive lug Vfor :cooperating therewith andsthat v'isiprojfected rearwardly so as to abut against the trigger member 14 thereot just above'ftheV finger.l grip .or trigger proper 15.

In the pistols of the patents mentioned a stop isprovided on the casing. for serving as the stop means mentioned.: In the present structure the dependent lug 3,7 on the lslide: 31 serves this function. Y

The hammer propelling arm 43 forms a V-shaped structure. with thel adjacent portion of the hammer body 45 thatprovides by its apex v46 a'ibearing for the, hammer member 44 in engagement with a post. 47. The hammer is positioned and generally operatively supported bymeans of the hammer spring 48. The striking face 49 isfattheuppreventing accidental removal ofV at an edge portion 34 per end and moves forwardly to meetV the anvil 50. f
